2 Claims.

My invention relates to safety razor sharpening arrangements.

In accordance with my invention, a safety razor has associated therewith a sharpening device which is manually operable in a convenient manner to sharpen the adjacent edge of a razor blade.

In a preferred form of the invention, the sharpening device is mounted on the razor for movement in opposite directions and along a path parallel with the edge of the razor blade which is to be sharpened.

Various other objects, advantages and features of my invention will become apparent from the following detailed description.

My invention resides in the sharpening means for safety razors, arrangements and features of the character hereinafter described and claimed.

For an understanding of my invention and for an illustration of some of the forms thereof, refz erence is to be had to the accompanying drawing, in which:

Figure 1 is an elevational View showing one form of my novel sharpening means for a afety razor blade;

Fig. 2 is a plan view of the safety razor arrangement shown in Fig. 1;

Fig. 3 is a vertical sectional view, partly in elevation, taken on the line 3-3 of Fig. 2 looking in the direction of the arrows;

Fig. 4 is a plan view illustrating one form of sharpening means constructed in accordance with the invention;

Fig. 5 is a perspective view showing a modification of the invention; and

Fig. 6 is a fragmentary, vertical sectional view illustrating another modification of the invention.

Referring to Figs. 1-4 inclusive, I have shown a safet razor having a handle I which, at one end thereof, comprises suitable means for clamping a safety razor blade 2 in shaving and sharpening position. As herein shown, this clamping means comprises a base 3 and a, cap plate 4 between which the blade 2 is disposed and held in suitable arcuate configuration by a screw 5 which extends loosely through the cap member 4, the blade 2 and the base 3,. the end of the screw 5 being threaded into the adjacent end of the handle I As shown, one side of the base 3 is of curved configuration, this curved section terminating in a guard member 31) having upstanding lugs or projections 30 at the respective opposite ends thereof against which the respective ends of the shaving edge of the blade seats.

In accordance with one form of the invention, a plate 6 is disposed between the base 3 and the handle I, said plate 6 being clamped in position by the aforesaid screw 5. As shown in Fig. 3, the cap plate 4 comprises a pair of spaced dependingmembers 2a which, when the parts are properly related to each other, extend, respectively, through alined passages provided therefor in the base 3 and the plate 6 to thereby hold said parts in proper assembled relation with respect to each other.

As shown, the plate 5 comprises side pieces 5a which are connected together by a bar or member l which is spaced below and disposed parallel with the adjacent edge of the razor blade 2. The

bar 1 supports a sharpening means which, as shown in Figs. 1 and 4, comprises an outermember 8 and an inner supporting member 9. these members being suitably shaped to form a section loosely embracing the bar i, said embracing section terminating in a handle section, the parts of which are fastened in position by a rivet l9, and the outer surface of the outer member 8 being covered with suitable. abrasive material as shown.

With the parts positioned as shown in Fig. 1, it will be understood that the sharpening means may be grasped by its handle section and elevated v into engagement with the adjacent edge of the razor blade 2. Thereupon, said sharpening means may be manuall moved in opposite directions on the bar 1, while contacting with said razor blade edge, to thereby sharpen the same to such extent as may be necessary. After the sharpening operation has been completed, the handle I may be rotated while holding stationary the various parts at the end thereof to thereby loosen and detach the screw 5 from said handle I. Thereupon, the position of the razor blade 2 may be changed to dispose the sharpened edge thereof in shaving position whereby, after the screw 5 has again been tightened, said sharpened edge comes into engagement with the lugs 30 at the end of the guard member 3b. By this operation, the edge of the razor blade 2 which, previously, was in shaving position, is now disposed in sharpening position and, as will be understood, the sharpening operation on said last named edge of the razor blade may be effected by operation of the sharpening means in the manner described above.

Referring to Fig. 5, I have shown the invention described above modified to the extent that the base 3 and the plate 6 are combined to form a unitary structure H which, as will be obvious,

embodies the combined features of said base 3 and plate 6. In some respects, the arrangement of Fig". 5 is a preferred construction because eliminating one of the parts shown in Fig. 1, namely, the plate 6.

Referring to Fig. 6, I have shown a modified form of the invention wherein the bar I is square in cross-section and is: embraced by a sharpening means having parallel sides joined by a top side disposed at right angles thereto. These parallel sides closely engage the respective opposite sides of the bar 'I which acts as a guide restricting the sharpening means for movement only in a vertical direction assuming that the device is posttioned as shown. With an arrangement of the character shown in Fig. 6, the top side of thesharpening means, during to-and-fro movement thereof and while elevated, flushly engages the tapered edge of the blade 2 to a degree dependent upon the upward pressure which is applied to said sharpening means. As will be understood, the arrangement of Fig. 6, when operated, sharpens therazor' blade more eifectively, in some respects than does the arrangement of Figs.- 1-4 inclusive.

The form of my invention shown in Fig. 6 is illustrative of a further detailed feature. Thus, as shown in said Fig. 6, the cap member 4' is flared upwardly and outwardly to some extent as indicated at 4a to thereby form a shield which protects the person operating the sharpening means from accidental cuts on the adjacent blade edge while operating the sharpening means. It will be understood that this shield arrangement, or

equivalent, may be used with the various forms of the invention as desired.

As regards the forms of my invention shown in Figs. 1-6 inclusive, it will be understood that other equivalent forms of sharpening means may be used in lieu of the one illustrated and described. Thus, for example, said sharpening means may be formed from sharpening stone, either artificial or natural, or from other equivalent sharpening material such, for example, as metallic material.

While the invention has been described with respect to a certain particular preferred example which gives satisfactory results, it will be understood by those skilled in the art after understand ing the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.

7 What is claimed as new and desired to be secured by Letters Patent is:

1. In a safety razor, a handle, means at one end of said handle for clamping a razor blade in fixed position, a support disposed adjacent an edge of said blade, and blade-sharpening means slidable in opposite directions on said support for sharpening said blade edge, said blade-sharpening means being manually movable as a unit transversely of said support toward or from aid blade edge.

2'. In a safety razor, a handle, means at one end of said handle for clamping a razor blade in fixed position, said clampin means comprising a base and a cap member between which said blade is disposed, a fixed bar disposed beyond said base adjacent an edge of said blade and parallel thereto, and blade-sharpening means slidable in opposite directions on said bar and engageable with said edge of said blade, said bar confining sai blade-sharpening means for movement substantially parallel with said blade edge, said blade sharpening means being manually movable as unit transversely of said support toward or from said blade edge.
